I'm working on UIMA Regex Annotator, and I'm wondering whether it is possible to use a Regex Variable inside another Regex Variable.
This is useful when we want to make long composite regex.
Say the first regex variable is "org_token" which matches any token
that is possible as a part of an organization name.
Then we also want to let "org_name" variable to include the variable
"org_token" in its description (like \v{org_token}).
